Claims. 1

This invention relates to liquid-elevating apparatus, having particular reference to that type of such apparatus in which an endless belt is disposed for operation in a well shaft, and wherein the upper portion of the belt is passed around a motor-actuated driving pulley arranged in a casing above the well shaft, and wherein the lower part of the belt passes around a weighted pulley submerged in the liquid to be elevated and disposed in the bottom of the shaft, the arrangement being such that when the belt is actuated,

. liquid adheres to the surfaces thereof and is conducted upwardly for discharge from the apparatus when the belt passes around the upper or driving pulley. Such apparatus has been disclosed, in general, in my prior patent, No. 2,391,642, dated December 25, 1945.

As such apparatus has been constructed heretofore, the same has necessitated the employment of a rigid frame, depending from the casing at the top of the well shaft, for effecting the support yof the lower pulley around which the liquid-submerged lower end of the endless belt passes, The employment of this rigid depending frame adds considerably to the cost of the apparatus and the length of the same is subject to variation in meeting the requirements of well shafts of different depth.

One of the objects of the present invention is to provide liquid-elevating apparatus of this character in which the depending well-shaft frame is eliminated and wherein cable-suspended means are provided, controllable from the top of the well shaft, for maintaining the lower pulley member of the apparatus in its required operating position.

Another object of the invention is to provide novel means, in liquid-elevating apparatus of the type under consideration, for maintaining the liquid-elevating belt under required tension and preventing twisting or undue distortion of the belt when positioned in a well shaft.

A further object of the invention is to provide a cable-suspended weight member for tensioning the liquid-elevating belt and, further, to provide said weight member and the lower belt pulley with a plurality of pivotally mounted arms, the latter carrying at their lower ends a plurality of sharp-edged disks, the arrangement being such that when the apparatus is suspendedin a lwell shaft, the arms are actuated to maintain the sharp peripheral. edges of the disk in contact with the well shaft lining, whereby to preclude rotation on the part of the lower belt pulley and twisting of the belt and without the employment of a rigid frame structure in the well.

For a further understanding of the invention, reference is to be had to the following description and the accompanying drawing, wherein:

Fig. 1 is a vertical sectional view, partly in side elevation, of liquid-elevating apparatus formed in accordance with the present invention;

Fig. 2 is a transverse vertical sectional view taken on the plane indicated by the line 2 2 of Fig. 1;

Fig. 3 is an enlarged vertical longitudinal sectional view taken through the upper portion of the apparatus;

Fig. 4 is a horizontal 4 4 of Fie. 1.

Fig. 5 is a front yelevational View, partly in vertical section, of the lower belt pulley and depending structure, disclosing a modied form of linkage for restraining the pulley against axial rotation.

Referring more particularly to the drawings, the numeral I designates the vertical bore or shaft of a well, containing liquid in the bottom thereof to be elevated, the bore or shaft being provided with the usual lining or casing 2, the open upper end of the bore or shaft being surrounded by a base 3 on which is mounted a housing .or casing 4. The latter may consist of a base section 5 having an opening 6 formed in the top thereof. Positioned on the base section is a top section 'I provided with a removable cover plate 8.

The top section is formed with longitudinally aligned bearings 9 for the reception of a shaft I0, the latter passing through a stuffing gland I I and being united by means of a flexible coupling I2 with the shaft of an electric motor I3, or other prime mover, which may be carried by a shelf I4, formingA a part of the base section 5 and projecting laterally therefrom.

Between the bearings 9, the shaft I0 is provided with an upper or drive pulley I5 and passing around this pulley is one or more endless belts I6.

The ascending and descending runs of the belt I6 depend in parallel order in the shaft casing 2, and at its lower end the belt passes around a, bottom pulley or guide sheave I'I, the latter being rotatably mounted on across shaft I8.

Positioned as at I9 Von the reduced outer ends of the shaft I8 is a pair of arms 20, and the lower ends of these arms are pivotally joined, as at 2|, to the upper ends of a pair of oppositely disposed bell crank levers 22. These levers are pivotally mounted on the intermediate portions of a shaft 23 which has its outer end portions positioned in registering openings 24 formed in the bifurcated upper end 25 of a weight member 25. The extreme outer ends of the shaft 23 are connected as at 21 with the lower ends of a pair of cables 28, the latter being employed in raising and lowering the weight member and the parts associated therewith.

To this end, the upper portions of the cables 28 are connected with drums 29 fixed on a transverse shaft 30 which is journaled, as at 3|, in
